A series of the composite lengths of hose are thenV coupled by means ofthreaded couplings such as the coupling I4 and the resulting line ofhose is manipulated as desired.

Figs. 3 and 4 show convenient end iittings Yand apparatus for use of thehose for well-drilling or well-pumping purposes, for example.

In Fig. 4 is` shown a series of driven pull-out and hold-back rolls Il,I8, I9 and guide rolls 2l) to 24 cooperating with a hose reel 25, hereshown as a vertical-axis reel and comprising a turn-table having ahorizontal, annular hose-supporting portion 26 and a vertical flange orspool portion' 21 against which the hose is Wound.
